Cross-Platform, Public Domain Simulation Tools For Performing Parametric Iaq And Energy Analysis, Stuart W. Dols, Lindsay J. Underhill

International Building Physics Conference 2018

As building design is being driven towards lower energy use, the relationship between indoor air quality (IAQ) and energy becomes more important due in large part to reduced building envelope leakage, which can lead to higher indoor pollutant levels. Simulation tools that can analyze building design measures that aim to improve IAQ and energy use are necessary for evaluating potential trade-offs involving such measures. This paper will present the use of CONTAM and EnergyPlus, coupled using co-simulation, to perform parametric analysis of IAQ and energy impacts. Both of these tools are available in the public domain and provide cross-platform methods …

Probing High-Momentum Protons And Neutrons In Neutron-Rich Nuclei, M. Duer, C. L. A. S. Collaboration, O. Hen, E. Piasetzky, H. Hakobyan, L. B. Weistein, M. Braverman, Gerard P. Gilfoyle, Et. Al.

Physics Faculty Publications

The atomic nucleus is one of the densest and most complex quantum-mechanical systems in nature. Nuclei account for nearly all the mass of the visible Universe. The properties of individual nucleons (protons and neutrons) in nuclei can be probed by scattering a high-energy particle from the nucleus and detecting this particle after it scatters, often also detecting an additional knocked-out proton. Analysis of electron- and proton-scattering experiments suggests that some nucleons in nuclei form close-proximity neutron–proton pairs with high nucleon momentum, greater than the nuclear Fermi momentum. However, how excess neutrons in neutron-rich nuclei form such close-proximity pairs remains unclear. …

Electronic Effect Of Platinum Alloy Catalysts On Olefin Hydrogenation Kinetics, Colin Reedy, Jeff Miller, Stephen Purdy

The Summer Undergraduate Research Fellowship (SURF) Symposium

Dehydrogenation of alkanes is the first step in transforming light hydrocarbons into liquid fuels and chemicals. This process has traditionally used platinum alloys as catalysts. Alloys are used industrially because they have a greater selectivity than monometallic platinum. Alloying platinum with an inactive promoter modifies the crystalline structure of the surface (geometric effect), and the 5d electrons in platinum responsible for chemistry (electronic effect); both have been suggested to be primarily responsible for dehydrogenation selectivity in platinum alloys. Alloy catalysts have been synthesized using early 3d transition metal promoters with the same Pt₃M crystal structure. X-Ray Absorption Spectroscopy …

Looking Toward The Future: The Value Of Geothermal Energy In The United States Power Market, Reilly R. Moran

STAR Program Research Presentations

States are creating renewable portfolio standards (RPSs) that require utilities to run off a certain percentage of renewables. With the new RPSs and current emission standards the dynamic of the grids energy and reliability needs are changing. Because RPSs and emission standards, utilities are procuring the cheapest renewable resources, which tend to be solar and wind. As RPSs increase over time this causes higher procurements of solar and wind. Higher procurement and increasing penetration levels of solar and wind is causing their energy values to decrease as well as some reliability concerns. While geothermal energy value will continue to stay …

Design Guidelines And Strategies For Thermal Solar Management Of Fenestration In The Desert Climate, David Mccredo

UNLV Theses, Dissertations, Professional Papers, and Capstones

This research evaluates the effects of varying thermal properties of windows in

residential energy use for the moderate altitude and 36'N latitude climate of southern

Nevada, which has a distinct cooling season. A selection of windows across different

shading conditions and total window areas were studied using BEopt energy simulation.

Findings demonstrate that for the specific climate, latitude, and altitude of Las Vegas,

Nevada, the most expensive “high performance” windows are not always the best

option in terms of total site energy use, and can be outperformed by properly shaded

less advanced windows. Under certain conditions, shading was found to …

Energy Calculations And Wave Equations, Ellen R. Hunter

MSU Graduate Theses

The focus of this thesis is to show how methods of Fourier analysis, in particular Parseval’s equality, can be used to provide explicit energy calculations for solutions of wave equations in one dimension. These calculations are discussed for simple examples and then extended to fit the general wave equation with Robin boundary conditions. Ideas from Sobolev space theory are used to provide justification of the method.

Thermoelectrics And Thermoelectric Devices, Benjamin T. Erck

Senior Theses

The field of thermoelectrics has many applications, and more are found in everyday systems. From its current studies, it is apparent that improving the figure of merit zT (which defines a good thermoelectric material) is important in the effectiveness of power generation. Another important part of thermoelectrics is the duality of these devices. They can both move heat and generate power, depending on their role in the system. In this thesis research, a process was made to test these thermoelectric relationships for a few Peltier devices in order to understand their efficiencies and what systems they can be applied to.

Mechanical & Aerospace Engineering Theses & Dissertations

Water demand is increasing at a rapid pace due to population increase, industrial expansion, and agricultural development. The use of desalination technology to meet the high water demands has increased global online desalination capacity from 47 million m^3/d in 2007 to 92.5 million m^3/d as of June 2017 [49]. Membrane and thermal processes are the two mainstream desalination categories used worldwide for desalination plants. Reverse Osmosis (RO) is the most widely used membrane process and it has become the dominant technology for building desalination plants over recent decades. Thermal distillation, however, has become less and less competitive due to its …

Saving Olivet Money With Creation Care, Nicholas Boros

Scholar Week 2016 - present

Universities throughout the United States are searching for ways to reduce overhead costs, to help combat rises in tuition costs. Typically, one would think that installing solar panels on campus to help generate electricity would cost Olivet money, especially since the University is located in the Midwest. While such an undertaking would require an upfront investment, we will discuss how solar panels could save the University as much as $500,000 to $800,000 per year after an approximate 10 year break even point. We will also briefly discuss how similar approaches could be applied to other businesses and homes for a …

Functionalized Nanoporous Carbon Scaffolds For Hydrogen Storage Applications, Christopher Carr

Dissertations

Recent efforts have demonstrated confinement in porous scaffolds at the nanoscale can alter the hydrogen sorption properties of metal hydrides, though not to an extent feasible for use in onboard hydrogen storage applications, proposing the need for a method allowing further modifications. The work presented here explores how the functionalization of nanoporous carbon scaffold surfaces with heteroatoms can modify the hydrogen sorption properties of confined metal hydrides in relation to non-functionalized scaffolds (FS). Investigations of nanoconfined LiBH₄and NaAlH₄indicate functionalizing the carbon scaffold surface with nitrogen can shift the activation energy of hydrogen desorption in excess of …

Rental Property Energy Efficiency In San Luis Obispo, Zachary Earl Shockley
